I can hear sound but when i press volume buttons (+ or -) on the earphones a volume level indication remains the same (but sound volume itself changes). I can move volume level sliders only with phone volume buttons. Thank you in advance for any help. Best regards

Hello alex.svch, Could you show me a short video of this problem? Does this always happen? Thank you.
